Abstract
The utility model relates to a friction plate, in particular to a copper-base powder metallurgy friction plate for forklifts. The copper-base powder metallurgy friction plate for forklifts comprises a mating steel plate provided with a middle fitting hole. 50 inner fitting teeth are evenly distributed at the edge of the fitting hole. Copper-base plates attached to the mating steel plate are arranged on front and back surfaces of the mating steel plate. Mesh grooves are evenly distributed on the copper-base plates. The copper-base powder metallurgy friction plate for forklifts is compact in structure, high in radiating performance, high in wear resistance, resistant to high temperature, high in base strength and long in service life.
Description
Technical field
The utility model patent relates to a kind of friction plate, relates in particular to a kind of fork truck copper based powder metallurgy friction wafer.
Background technique
At present traditional friction plate assembly performance is poor, and assembly precision is not high, and friction factor is low simultaneously, and the product loss is fast, and the friction disk heat dispersion is poor, can't be effectively discharge during the heat utmost point that produces, cause friction plate to reduce working life.
Chinese patent 200920207215.5, a kind of friction plate is disclosed, the friction plate that comprises ring-type is distributed with on two rubbing surfaces of described friction plate on the rubbing surface of fin or described friction plate and is distributed with fin, is distributed with the oil storage pit on another face of this friction plate.The wear resistance of this structure is relatively relatively poor, and working life while is shorter, and maintenance cost is high.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, and a kind of compact structure is provided, and wear resistance is high simultaneously, has guaranteed the Safety performance of vehicle, has improved the fork truck copper based powder metallurgy friction wafer of friction factor and high-temperature behavior.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of fork truck copper based powder metallurgy friction wafer, comprise pairing steel sheet, be provided with pilot hole in the described pairing steel sheet, the edge of described pilot hole is provided with equally distributed interior assembling tooth, the number of teeth of described interior assembling tooth is 50, the surface of described pairing steel sheet and the back side are respectively equipped with the copper base that fits with it, and described copper base is provided with equally distributed meshed groove.
This Standard performance is good, and the meshed groove thermal diffusivity is good simultaneously, improves the quality of product.
As preferably, described meshed groove is two arc grooves.
Therefore, fork truck copper based powder metallurgy friction wafer of the present utility model, compact structure, thermal diffusivity is high, and wear resistance is good, and is high temperature resistant, and matrix strength is high, long service life.
